Conservation of matter states that the reactants have to equal the products enablers 2. products and reactants in a balanced chemical reaction have the same number of of each element. atoms molecules 3. if the equation on the board had shown 3 atoms of carbon on the reactants side, how many atoms of carbon would need to be represented on the products is

1) Conservation of Matter states that the reactants have to equal the products.
2) Products and reactants in a balanced chemical reaction have the same number of atoms of each element.
3) Three (3) atoms of carbon would need to be represented.
Number of atoms on the left and on the right side of the balanced chemical reaction is the same, for example: Mg + 2HCl → H₂ + MgCl₂. There are two hydrogen atoms, two chlorine atoms and one magnesium atom on both side of chemical reaction.

1) Conservation of Matter states that the reactants have to equal the products.

2) Products and reactants in a balanced chemical reaction have the same number of atoms of each element.

3) Three (3) atoms of carbon would need to be represented.

Explanation:Number of atoms on the left and on the right side of the balanced chemical reaction is the same, for example: Mg + 2HCl → H₂ + MgCl₂. There are two hydrogen atoms, two chlorine atoms and one magnesium atom on both side of chemical reaction.

The answer would be 1.5 kJ.

Explanation:

When you use the equation q = m x c x ∆T you will be able to find the energy gained or lost. The data for the water in this case is just there to distract you so ignore it. :D
